Flora 14: 459. 1831
Mostly temperate Asia, also North America, Mexico, and Africa.
The phenomenon of sex changing in Arisaema has been investigated by many authors (e.g., P. Bierzychudek 1982; K. Clay 1993; E. Kinoshita 1986). Smaller plants produce only staminate flowers, and larger plants produce either staminate and pistillate flowers simultaneously or pistillate flowers only. Changes in gender expression are directly correlated with size and are also influenced by the environment in which the plants are growing. Reversions in phenotypic gender have been experimentally induced by such factors as removing leaf area or changing soil nutrient levels.
Although some species are cultivated as ornamentals, the genus is not of great economic importance.
Species ca. 170 (2 in the flora).
